Waste flexible polyurethane foam (FPF) is an environmental pollutant lacking sufficient recycling technology for its removal. Therefore, we investigated experimentally whether waste FPF could be pyrolyzed and used as a diesel fuel. Waste FPF was pyrolyzed in rapeseed oil at 320℃ using 0.3wt% Ca (OH)2 as a pyrolysis accelerator. The FPF-pyrolyzed oil (PO) was mixed with kerosene (KE) as a diluent at various ratios, and these oil mixtures were evaluated as diesel fuels. For each fuel composite, we investigated the viscosity, calorific value, fuel consumption, and the amount of power generated by a dynamo attached to the diesel engine. In addition, a compositional analysis was performed on the combustion exhaust gas. In this study, the viscosity of PO decreased remarkably in proportion to the amount of KE, but the calorific value increased. The exhaust gas from a 30:70 mixture of PO and KE was tested for NOx emissions using an air pollution gas element detector. The NOx concentration was found to be about 1.2-9.2% lower than that of regular diesel fuel. In addition, the CO2 concentration increased with the number of revolutions and the SOx concentration was not contained in each composite fuel. However, the fuel consumption of the KE composite fuel increased by about 4-5.9 times compared with regular diesel fuel. The power generation performance was almost equal to that of diesel oil fuel on the market. Therefore, PO/KE composite fuel can be used as a diesel fuel.Keyword: Flexible Polyurethane Foam, BDF, Recycle, Diesel oil, Kerosene
